Abstract:
A method for evaluating antifoam additives for lubricants. The method includes a step of aging a quantity of fluid containing an antifoam additive in one or more high shear simulator(s) for a period of time to provide an aged fluid. After the aging step, the fluid is evaluated in a foam tendency evaluation test to provide the foaming tendency for the fluid.
